Our take
WTO150's key difference is a two-part design: an oven section sits beside a separate pop-up toaster. The manual shows four items arranged on the oven rack and permits using the toaster while the oven is set to oven, bake, or toast; during that overlap the oven's lower heating element is off. The oven side has Bake, Broil, and Toast, while the toaster has separate shade controls and a Bagel button. The manual names a 450°F/Broil/Toast position but gives no full bake range. Lowe's says a 12-inch pizza does not fit.
For buyers who want both toaster slots and a small oven rack, with at least four inches open on every side..
Not for a 12-inch pizza, a long timed oven cycle, use beneath a wall cabinet or in an appliance garage, or air-fry/convection cooking.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- A separate slot toaster and oven rack provide two different toast methods.
- The manual describes simultaneous use and its lower-element condition.
- Four-inch all-side clearance and household-use limits are documented.
What to weigh up
- The oven timer reaches 30 minutes; ON is not a longer timed interval.
- A 12-inch pizza does not fit, and smaller pizza or pan dimensions are not stated.
- The combined toast count must not be treated as a six-slice oven-cavity rating.

What the features mean for you
Two appliance sections do different jobs
WTO150 pairs a toaster oven with a separate pop-up toaster. Waring's booklet describes Bake, Broil, and Toast on the oven side; the pop-up toaster has its own shade control and Bagel button. The manual shows four pieces arranged on the oven rack. Lowe's exact-model record also lists four-slice oven capacity. These separate compartments are useful for a kitchen that uses both formats, but their capacity claims should be kept distinct.
Concurrent use has a heat tradeoff
The manual permits the toaster and oven/bake/toast function to run together, with a specific limitation: the oven's lower heating element turns off during that overlap. That is a documented way to coordinate two routines, not evidence that both sides have independent full heating while used at once. Plan around the lower-element condition if a timed oven dish needs heat from both directions.
Count toast by compartment
The oven side has a four-item layout, and the separate pop-up toaster has two slots. The six positions are distributed across distinct compartments; they do not make the oven a six-slice cavity. The manual says both parts can be used at the same time, subject to the lower oven heater switching off. Keep that condition in mind when comparing it with an oven that publishes a single six-slice arrangement.
Clearance, timer, and dish size
Waring calls for at least four inches of open space on every side and says not to operate WTO150 under a wall cabinet or in an appliance garage. Lowe's exact-model record provides outside dimensions and says a 12-inch pizza does not fit. The saved sources give no smaller pizza diameter or pan footprint. The oven timer runs up to 30 minutes and also has an ON position; the separate ON setting is not a longer timed cycle.
Household use and exact-model limits
The Waring booklet names WTO150 on its cover, says household use only, and warns against unattended operation. Its first-use instructions identify a 450°F/Broil/Toast selector position, not a complete adjustable baking-temperature range. Historical renewed/refurbished titles and ASINs do not identify a current offer or condition. Search the exact WTO150 code, compare the seller's current details, and do not use the Pro name as proof of restaurant-duty operation.
What else to compare
Choose a single-cavity model with a published pizza diameter if oven-side cookware fit is the priority.
Before you buy
Can I use both the toaster and oven together?
The manual permits concurrent use, but the oven's lower heating element turns off during that time.
Is this a six-slice oven?
No. The oven side has a four-item layout; two separate toaster slots are a second compartment.
Will a 12-inch pizza fit?
Lowe's exact-model record says a 12-inch pizza does not fit; no smaller diameter is stated.
How long can I set the oven timer?
The manual shows a 30-minute timed setting and a separate ON position, not a longer timed cycle.
Can it be placed under a cabinet?
The manual says not to operate it under a wall cabinet or in an appliance garage.
